Cl. 4--1 20 Claims ABSTRACT OF THE DISCLOSURE An enclosed room has three bathroom fixtures in it: a lavatory and counter, a toilet and a urinal. The urinal and toilet are each carried by a rotation joint or hinge for rotation into a cleaning position nestled below the lavatory and counter. Plumbing to the toilet and urinal is through their rotation joints and includes rotational plumbing joints to swing with these fixtures. Cleaning spray heads beneath the lavatory and counter are positioned to direct cleaning solution into the urinal basin and onto the toilet. Cleaning spray heads behind the toilet are positioned when the toilet is in its cleaning position to direct cleaning solution onto the under surface of the urinal basin. Rotatable panels carried by the rotation joints of the toilet and urinal close upon themselves when the urinal and toilet and rotated into their cleaning position to define a cleaning cabinet for all three fixtures. Additional nozzles within the cabinet clean the walls, a mirror and the floor during the cleaning operation. Outside the cabinet, the walls of the enclosed room are conveniently cleaned with additional spray heads without being encumbered by the urinal and toilet. The cleaning equipment is self-contained in a support package. Circulated hot air dries the cleaned fixtures and walls of the restroom.

BACKGROUND OF THE INVENTION The present invention relates to a self-cleaning restroom and, in particular, to a self-cleaning restroom wherein fixtures close on themselves into a cleaning position where they are cleaned and where the walls of the restroom are freed for their cleaning.

Clean restrooms in public facilities are absolutely necessary for hygienic reasons. But, in addition, clean restrooms serve the reputation of the proprietors of the facilities. U nfortunately, cleaning of restrooms, particularly in public facilities, requires a considerable amount of time and is an unpleasant task at best. The task of cleaning restrooms is made difiicult by the restroom fixtures themselves, for the fixtures have surfaces in out-of-the-way places and mask restroom Walls which should be cleaned periodically.

There is a need therefore for some means to improve upon the time honored way of cleaning restrooms and to free attendants for more productive tasks while insuring that the restroom facilities are always clean.

SUMMARY OF THE INVENTION The present invention provides a self-cleaning restroom which is characterized by having the restroom fixtures close upon themselves in a cleaning position for efiicient cleaning and freeing of the enclosing rooms walls for ease of their cleaning.

, One form of the present invention contemplates an enclosed room which serves as the enclosure of a restroom during normal usage. It typically is provided with an access door to the restroom. At least two restroom fixtures are in the room, typically a toilet, and a lavatory in a counter. A rotation joint or hinge carries one of the fixtures for rotation from an in-use position to a cleaning position in close proximity tothe other fixture. Plumbing to the fixtures is ofcourse provided. The plumbing includes means for rotating the plumbing of the rotatable fixture with that fixture between the in-use and the cleaning position without uncoupling or damaging the plumbing. This is conveniently accomplished by having the plumbing to the rotatable fixture extend for a length in the rotation joint for that fixture and then extend to the fixture through a rotating joint or flange of its own. Means are also provided for cleaning the fixtures in their cleaning position. These means may include spray heads or nozzles oriented to direct a spray of cleaning solution over the surfaces of the fixtures. These means may also include means such as spray heads for cleaning the walls of the restroom and other attendant accessories.

In preferred form, the toilet in the cleaning position is nested under the lavatory and counter, and the cleaning means includes spray heads disposed under the wash basin to clean the toilet. Rotatable panels carried by the rotatable fixture are also preferably provided to define, in the fixtures cleaning positions, a cleaning cabinet which is smaller than the enclosed room.

The cleaning means is conveniently packaged in a support unit and may have a sump for cleaning solution, a heater for heating the cleaning solution, a pump for providing the pressure required by the cleaning solution through the spray heads, and dispensers for cleaning chemicals, disinfectants and the like. The restroom may also be provided with a drying system which includes ducts, a hot air heater, a blower for discharging the hot air into the cleaning cabinet, as well as the outside room, and inlet and exhaust vents for the drying air. Desirably, the cleaning cabinet is sealed from the room outside of the cabinet through appropriate seals.

One specific form of the present invention contemplates an enclosed room having an access door for entrance and exit from the room. Within the room are three bathroom fixtures: a urinal, a lavatory and counter, and a toilet. The toilet and urinal are each carried by a rotation joint for rotation joint for rotation from an in-use position to a cleaning position. In the cleaning position, the toilet and the basin of the urinal are disposed under the lavatory and counter for cleaning by spray heads, also disposed under the counter. A partition between the lavatory and counter and the toilet carries a door to the toilet to provide privacy. The partition is hinged so that is can swing out of the way when the toilet is rotated into its cleaning position. The rotation joints of the urinal and toilet are spaced from the walls of the enclosing room, that is, they extend out into the room, and flank the lavatory and counter. Generally L-shaped carriers support the urinal and toilet from their rotation joints. These L-shaped carriers, when rotated into their cleaning position, provide portions of two side Walls or panels of the cabinet and a back wall of the cabinet. Either the toilet or urinal carrier may have a swing closure panel, if necessary, which rotates out of a stored position to complete the back panel. The equipment storage package is conveniently placed in a vertical enclosure in back of a mirror which faces the lavatory and counter. A sump below the lavatory and counter provides for drainage of cleaning solution.

These and other features, aspects and advantages of the present invention will become more apparent from the following description, appended claims and drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention provides a self-cleaning restroom wherein restroom fixtures move out of their in-use position into a nested position for their eificient cleaning. With the movement of fixtures away from their in-use position, the walls of the restroom are unencumbered by the fixtures and, as such, can also be readily cleaned.

FIGS. 1 and 2 illustrate, somewhat schematically, plan and elevational views of the improved restroom. In these figures, the enclosing walls of the restroom which define with a ceiling and a floor an enclosed room are indicated at 10 by the single encompassing solid line. Within the enclosed room defined by wall 10 are a toilet 12, a lavatory and counter (wash basin and counter) 14, and a urinal 16. A mirror 18 behind the lavatory and counter extends vertically upward from it. The lavatory and counter includes a counter proper 2t and a basin 22.

With continued reference to FIGS. 1 and 2, the lavatory further includes a cabinet 24 which has a pair of doors 26 hinged in place. These doors swing open to accept the toilet and urinal basin during cleaning. The cabinet may be defined by stationary support partition mountings or walls, in which case the doors are hinged on these mountings.

Again with reference to FIGS. 1 and 2, the toilet includes a bowl 28 and a lid 30 in standard fashion. For its part, urinal 16 includes a basin 32.

Both toilet 12 and urinal 16 are rotatably carried by an associated rotation joint. In FIGS. 1 and 2, the rotation joint for toilet 12 is indicated by reference numeral 34 and the rotation joint for urinal 16 is indicated by reference numeral 36. A toilet carrier 38 provides the actual carriage for toilet 12 and is itself carried by rotation joint 34. Similarly, a urinal carrier 40 provides the actual carriage for urinal 16 and itself is carried by rotation joint 36.

An access door 42 opening in the are shown provides access to the restroom from outside. A partition 44 carries an access door 46 to the toilet. The access door and its carrying partition 44 are hinged at 48 from wall 10 to open for restroom cleaning in the arcs shown.

An equipment support package 50 extends vertically to the rear' of lavatory and counter 14 above mirror 18 and then over the lavatory and counter as shown in FIG. 3.

A full height partion mounting 52 and a full height panel 54 flank the sides of lavatory and counter 14 and extend into the restroom to rotation joints 34 and 36, respectively. These are the mountings which may define cabinet 24 and hinge doors 26. This full height partition and panel provide the mounts for the rotation joints and form a part of the cleaning cabinet when the restroom fixtures are in their cleaning orientation. A station- 4 ary back, full height panel 56 extends the height of the restroom and with mountings 52 and 54 provides the mounting for lavatory and counter 14. Partition mountings 52 and panel 54 extend from the back partition mounting at right angles to it.

A sump 58 below the floor of the restroom provides a basin for restroom cleaning solution.

With reference to FIGS. 1 through 3, toilet carrier 38 more specifically includes a full height back panel 60 for cabinet closure. A second full height lateral or side panel 62 of the toilet carrier extends at right angles to panel 60 and also serves a cabinet closure function. An L-shaped carrier beam 64 supports toilet 12 and itself mounts panels 60 and 62 for rotation about the rotational axis of rotation hinge 34. The back panel 60 meets beam 64 at a step 66 so that the beam can rest against the wall of the restroom during in-use orientation.

Complementing the full height panel-s of the toilet carrier are similar panels on urinal carrier 40. A full height back panel 68 is disposed at right angles to a full height side panel 70. A urinal support beam 71 carries the panels and supports urinal 16 and rotates about the vertical rotational axis of rotation joint 36. In the open position shown in FIG. 1, a swing closure panel 72 is shown hinged at 74 to urinal carrier 40. This swing closure panel also extends for the full height of the restroom and in storage rests in a recess 76 of the urinal carrier in order that the urinal in its open position may be as close to the bounding wall of the restroom as is possible. Recess 76 extends beyond hinge 74 towards urinal 16. In other words, hinge 74 extends slightly outwardly of the back wall of recess 76. Cooperating faces 78 and 80 of swing closure panel 72 and urinal carrier 40 cooperate to provide a stop for the swing closure panel in its open position.

While FIGS. 3 through 7 show the cleaning cabinet and attendant fixtures in their washing position, FIGS. 5 through 7 illustrate to best effect cabinet closure and definition.

With reference initially to FIG. 5, toilet 12 is shown rotated into its cleaning position. In the cleaning position, doors 26 of the lavatory and counter cabinet are open. Carrier 38 and its carried toilet 12 have been rotated 180 from their in-use position to their cleaning position. It should be noted that the toilet is spaced sufiiciently from side panel 62 and a portion of the carrier abutting the side panel to clear full height partition mounting 52 as the toilet rotates the 180. In place in the cleaning position on the toilet resides essentially completely under lavatory and counter 14, not shown in FIG. 5.

Urinal carrier 40 rotates about hinge 36 180 to its cleaning position. Swing closure panel 72 is rotated about hinge 74 from recess 76 180 until faces 78 and 80 abut. A full height seal 82 in one or the other of these faces is compressed by the faces abutment to aid in the closure of the cabinet. Cooperating faces 84 and 86 'of a step section 88 of swing closure panel 72 and panel 60 abut one another in the closed position. A full height seal 90 in one or another of these faces is compressed by them to seal the interior of the washing cabinet.

FIG. 6 illustrates the closed position of urinal 16. Basin 32 of the urinal nests in under lavatory and counter 14 just outside doors 26. The nesting of the basin can best be seen in FIG. 3.

FIG. 7 merely illustrates the top of the lavatory and counter 14 with the urinal basin and toilet being hidden from view.

The plumbing to the various fixtures is operable to rotate with the fixtures from their in-use position to their cleaning position. FIGS. 2, 3 and 4 illustrate a suitable plumbing arrangement for toilet 12. A line 92 of the plumbing extends into rotation point 34 and extends for a distance along the rotation joints rotational axis. A rotation flange 94 rotatably couples line 92 to line 96 which extends into the toilet itself. Thus, upon rotation of the toilet, line 96 rotates with respect to line 92 by virtue of flange 94 and the plumbing does not come uncoupled. Essentially identical approaches are taken for the plumbing for urinal 16 and for cleaning spray heads behind the toilet are but not shown for clarity.

As previously mentioned, it is desirable to seal the cabinet from the rest of the room during the washing operation. FIGS. 8 and '9 show a typical seal arrangement which would be useful for this purpose.

In FIG. 8, a floor 98 of the restroom is shown. A typical cabinet wall 100, as one of the rotatable panels previously described, mounts a seal 102. A force bar 104 is disposed over a laterally projecting portion of seal 102 to compress the seal tightly against floor 98. Actuation of force bar 104 may be by a hand lever, not shown, which pulls on an actuator bar 106, which in turn acts through a series of levers 107, pivotally connected to wall 100 through pivot pins 108, to'compress seal 102 tightly against the floor 98. The levers shown are overcenter levers so once seal compression is effected it will be maintained until the hand lever is actuated to release the seal.

FIG. 9 illustrates a seal arrangement suitable for walls and ceilings. As previously brought out, wall seals 82 and 90 are required to prevent unnecessary amounts of cleaning solution from entering the room outside the washing cabinet. In addition, of course, ceiling seals will also have to be used where there are movable panels. A suitable seal is shownin FIG. 9 by reference numeral 109. Is is a compression seal and is acted upon by two members 110 and 112, say, a panel and a ceiling.

FIG. shows a typical system which would be suitable for drying the cabinet and exterior room after it has been washed. A blower 114 takes atmospheric air and discharges it under moderate pressure into an air heater 116. The heated air leaves heater 116 and enters the enclosed washing cabinet denominated by the boundary shown in phantom in FIG. 10. The hot air enters through the ceiling, above lavatory and counter 14, below the counter, and into other areas of the cabinet. If desired, hot air from the same source can be used in the balance of the restroom, as indicated in the figure. Exhaust vents are of course provided for discharging the air from the cabinet and the room. These exhaust vents are shown in parallel circuit and are indicated by reference numeral 118.

FIG. 11 illustrates a suitable washing system proper. In the system, sump 58 receives water through line 120. A solenoid operated valve 122 controls the flow of water into the sump. A sump heater 124 serves to heat the water and cleaning chemicals in sump 58 to the desired temperature. Dispensers 126 and 128 through respective solenoid valves 130 and 132 are operable to selectively discharge detergents, germicides, wetting agents and the like into sump 58. A liquid level control 134 maintains the proper level of liquid in the sump. A pump 136 between a plurality of cleaning spray heads 138 supplies the pressure necessary for effective cleaning through the spray heads. A solenoid valve 140 is in the line between the spray heads and the pump. A second solenoid valve 142 in a waste line determines whether the pump supplies that line. When valve 140 is open and valve 142 is closed, cleaning solution is passed through the spray heads for their cleaning function. When the converse is true, valve 140 is closed and valve 142 is open, and the sump is cleared of the cleaning solution.

A first set of spray heads 138a are in the ceiling of the cleaning cabinet and possibly the outer room for directing cleaning solution against exposed walls and the like. A second series of these spray heads 13812 are disposed in the side walls of the cabinet and are directed inwardly to clean these walls and other exposed surfaces. A third of these series of spray heads 138a appear to best effect in FIG. 3 and are disposed under lavatory and counter 14 to clean the urinal basin and the toilet. A fourth of these spray heads 138d may be disposed behind the toilet to clean the Wall supporting the urinal and the bottom portions of the urinal unnder the urinal basin. As previously noted, the same type of rotating joint used and specifically illustrated with reference to the waste line rotating joint of the toilet may be used for the cleaning system to the spray heads behind the toilet. As such, rotating joints within rotation hinge 34 enable the system to rotate with the toilet from an in-use position to the cleaning position without damage to the cleaning plumbing or uncoupling it. A fifth of this series of spray heads 138e may be directed out of the cleaning cabinet into the restroom proper to clean its walls, ceiling and floor. i 1

-'While the operation of the present invention is believed to have been adequately described before, a brief description of the operation will be presented here. In the in-use position, the restroom appears as it does in FIGS. 1 and 2. When it is time to clean the restroom, full height partition 44 is swung out of place. Toilet carrier 38 is rotated 180 to bring the toilet through doors 26 below lavatory and counter 14 in the position shown in elevation in FIGS. 3 and 4. Urinal carrier 40 isrotated about rotation joint 36 180. Swing closure panel 72 is rotated into place 180 such that step section 88 abuts back panel 60 and seal is fully engaged and compressed. Also, seal 82 should be fully engaged and compressed. When both the urinal and toilet are rotated into their cleaning position, the appearance of the resulting cleaning cabinet appears to best effect in FIG. 3. It should be noted here that the interior of the cabinet is very compact. The urinal basin and toilet both use available space under the lavatory and counter. Mirror 18 is in position to be cleaned.

After the toilet and the urinal have been rotated into position and their panels secured to define the closed cleaning cabinet, the floor seals in the rotatable panels are brought into sealing engagement with the floor. Access door 42 to the restroom is closed and locked. Once this is accomplished, the cleaning operation can begin. In the cleaning operation, sump 58 is filled with water which is heated by heating element 124. Suitable detergents, wetting agents, sanitizing agents and the like are dispensed from their dispensers 126 and 128 through solenoid valves and 132. During the cleaning operation, the level of cleaning solution in sump 58 is maintained by liquid level control 134. Pump 136 is actuated, valve opened and valve 142 closed. Cleaning solution will then spray in the desired and described patterns from the plurality of spray heads throughout the interior of the cleaning cabinet and into the restroom proper, as previously described. After cleaning, valve 140 is closed and valve 142 opened to discharge the contents of sump 58 into a waste line.

After cleaning, blower 114 and air heater 116 are operated to dry the cleaned restroom including its fixtures with hot air. Air is exhausted to atmosphere through exhaust vents 118.
